State officials said Wednesday that reviews have been completed on provisional balloting in all but three counties in the 4th Congressional District, and U.S. Rep. Scott DesJarlais maintains the lead.

The Secretary of State's office released figures showing that 87 provisional ballots were cast in 13 of the district's 16 counties, including those cast in the Democratic primary and local general elections only. Of those, 10 have been ruled to be valid Republican votes, with DesJarlais taking four and Tracy two.

Results are pending in Sequatchie, Warren and Grundy counties.

The tally means DesJarlais, R-South Pittsburg, still has a 37-vote lead over Tracy in the Republican primary. The winner will take on Democratic nominee Lenda Sherrell and independent Robert Rankin Doggart in November.

Voters in Tennessee can cast a ballot provisionally for a number of reasons. Tennessee law allows provisional balloting if a voter lacks photo identification, but he or she must return to the election commission within two business days of the election to show ID.

Tennesseans also can cast a provisional ballot if their names do not appear on voter rolls. In those instances, officials are required to check their names against other records.

The ballots are sealed so election officials do not see the votes until after a determination of eligibility has been made.

DesJarlais holds a lead of less than five-hundredths of a percentage point. The campaign for Tracy, R-Shelbyville, said it does not plan to decide whether it will challenge the outcome until all election commissions in the district have certified their results, a process that could stretch into next week.

The campaign has five days after the election is certified to request a recount.
